Abstract: M67.00009 : Quantum Optomechanics with Superfluid Helium*
9:36 AM–10:12 AM
I will also describe ongoing efforts to realize Fock states and entangled states in the next generation of our optomechanical device (with a resonator mass ∼ 10 μg), and recent work to generate and probe coherent states of the mechanical resonator (displaced thermal states with <n> ∼ 40,000, <(Δn)2> ∼ 1). A sensitive measurement of their coherence allows us to bound the quantum gravity induced non-locality length scale to < 10-18 m , comparable to the bound given by experiments at the Large Hadron Collider (< 10-19 m).
